Senior Systems Engineer – London (Hybrid)
In-Vitro diagnostics · Complex systems · High-growth environment
6-12 month contract, highly competitive rate, inside IR35.
Are you a Systems Engineer with deep experience in IVD or medical device development, looking to play a key role in bringing a revolutionary new diagnostic platform to market?
This is an opportunity to join a fast-growing, multidisciplinary team working at the forefront of molecular diagnostics, where you’ll shape system architecture, lead technical problem-solving, and influence the direction of an entire platform.
The Opportunity
As a Senior Systems Engineer, you’ll work across engineering, science, software, and quality teams to define system requirements, develop system architecture, and ensure robust traceability across the full product lifecycle. You’ll also guide and mentor colleagues as the team advances a complex electro-mechanical instrument and consumable system through development.
You’ll be hands-on with system modelling, experiment design, integration work, and the development of innovative approaches to solve challenging technical problems. This role is ideal for someone who thrives in dynamic, fast-paced environments and enjoys working on cutting-edge technology with real-world impact.
Key Responsibilities
-
Define system requirements, system architecture, and risk/requirements traceability for a next-generation IVD platform.
-
Work closely with external developers and contractors to ensure clear communication of system needs.
-
Lead design reviews and contribute to product development planning.
-
Produce and maintain key system design documentation and traceability matrices.
-
Mentor colleagues across a multidisciplinary engineering and scientific team.
-
Apply systems engineering principles to create reliable, cost-effective, and compliant designs.
-
Design, execute, and analyse experiments to verify system requirements.
-
Define and negotiate engineering trade-offs to achieve optimal system performance.
-
Lead system integration efforts and champion best practice in Systems, Reliability, Risk, Usability and Requirements Engineering.
-
Keep abreast of state-of-the-art developments in systems engineering and reliability.
-
Conduct technical reviews and contribute to technical strategy.
-
Develop novel approaches to overcome product development challenges.
-
Maintain quality records across chemistry, consumables, and instrument activities.
-
Ensure documentation complies with ISO 13485 requirements in collaboration with Quality.
About You
You’ll bring a strong background in systems engineering within IVD, diagnostics or closely regulated medical technologies — plus the ability to influence, collaborate, and drive technical rigour.
